Samsung t220 problem screen goes off and on again and again

[Arjunny]

Hello,
I need help for my Samsung T220. Few hours back it suddenly started going blank for a few seconds and then come back again for few seconds and then blank again..this cycle is repeating itself again and again. And every time it keeps auto adjusting itself.

Check cables. Does this happen in all applications or only games?

Have it tried it on another computer?
